• Enrichment: start from a SCIAN segment and feed the list to your enrichment waterfall or CRM.

What makes it B2B

DENUE lists ~6.1 million establishments, and most of them are corner shops run by natural persons. This actor turns it into a company list:

	DENUE as published	This actor
Who	Every establishment, ~79% of them natural persons (no legal name)	Legal entities only, always (no switch: company data only)
Public sector	Mixed in (schools, offices, hospitals)	Excluded by default (exclude_public_sector)
Industry	SCIAN code + Spanish label	Spanish class label + English subsector and sector labels
Size	Text bracket ("11 a 30 personas")	Bracket filter + min_employees + numeric bounds
Phone	Free text	+52 + 10 digits, junk dropped
E-mail	Free text: personal mailboxes, Gmail/Hotmail/Prodigy, typos	Role mailboxes on the company's own domain only (contacto@, ventas@, facturacion@…); personal and free-mail addresses blanked
Website	Free text (WWW.X.COM, Facebook pages), never checked	https:// URL; social pages split into social_url; website_guess from corporate e-mail domain; website_verified after an HTTP check (272,768 DENUE establishments verified)
Branches	One row per establishment	Optional one_per_company (largest establishment per legal name)

Website filters: which one to use

Filter	Keeps an establishment when	Use it for
none (default)	always; web fields may be empty	full universe, TAM counts
only_with_website	it has a website declared to INEGI or a website_guess (the domain of its corporate e-mail). Not checked: may be dead or parked	widest list with a domain to enrich
only_with_verified_website	its site answered our HTTP check (2xx/3xx, not parked, for sale, suspended or a hosting default page); the final URL is website_verified_url	outbound lists where the site must be live

only_with_verified_website is a strict subset of only_with_website. Free-mail, ISP, hosting, social-network and placeholder domains (gmail.com, prodigy.net.mx, contacto.com, wix.com, …) never count as a website: they are blanked in website, website_domain, website_guess, website_verified_url and email_domain at output time. Social pages are in social_url.

Public company contacts from the verified homepage

What. For establishments with a verified website we read the homepage itself and return the contacts the company publishes there: role e-mails (public_role_emails: contacto@, ventas@, info@, atencion@, facturacion@, ...), phones (public_phones, +52 + 10 digits), and the company's LinkedIn, Instagram and Facebook pages. Every value comes with the page it was read from (contact_source_url) and when (contact_fetched_at, UTC). This is the contact a buyer would find by visiting the site; the contact filed with INEGI stays in phone / email.

How. The homepage of every HTTP-verified domain (see website_verified) is fetched once (one page, no crawling, no login, no forms), and e-mails, tel: links, phone numbers and social links are extracted from the HTML. The contact is matched back to the establishment through its declared website domain, then its corporate e-mail domain.

Two flags, one filter.

• has_public_contact: the homepage gives this establishment any company channel: role e-mail, phone or a social page (LinkedIn/Instagram/Facebook).
• has_public_email_or_phone: it gives a role e-mail or a phone, i.e. something you can e-mail or call.
• only_with_public_contact: true keeps the rows with has_public_email_or_phone = true; social-only pages don't count.

Rules (company data only).

• Only role / generic company mailboxes are output, under the same strict rule as email (see "E-mail rule" below): contacto@, ventas2@ pass; juan.perez@, ventas.juan@ don't. Free-mail addresses are never output, and an e-mail must be on the company's own domain.
• Phones must be valid Mexican numbers: +52 + 10 digits, first digit 2-9. The obsolete mobile prefix 1 (+52 1 ...) is removed; nothing is added. Placeholder numbers (one digit repeated, 1234567 sequences, 666 666 6667) are dropped.
• A value found on more than 3 different company homepages (a web agency's footer, a template placeholder) is dropped.
• Branches of one company share its contact. DENUE lists establishments, so a chain's stores all point to the same site. When every establishment on a domain has the same razón social (accents, punctuation and the legal form such as S.A. de C.V. ignored), the site's contact is that company's and every branch gets it.
• When a domain is used by different companies (a group's shared site, a reseller, a franchise portal) or by an establishment without a razón social, the contacts on that site are not attributable to this one establishment: nothing is output, only the flag contact_is_shared_domain is set.
• Social links are company pages only (LinkedIn /company/, brand Instagram/Facebook); personal profiles are discarded.

Field notes

• Legal entities. INEGI publishes the legal name (razón social) only for legal entities and usually strips the corporate suffix (S.A. de C.V., S. de R.L., …). is_legal_entity is true when the name carries a legal form, or when a legal name is present and doesn't look like a person's name or a placeholder. legal_entity_basis says which rule fired (every output row carries it). Rows with a person-like name are treated as uncertain and never returned.
• website is what the establishment declared to INEGI. website_guess is https:// plus the corporate e-mail domain; free-mail, Mexican ISP (Prodigy/Telmex, Axtel, izzi, Megacable…), placeholder (contacto.com, correo.com.mx, …) and typo domains are never used. Neither is checked by itself; see the next note.
• website_verified_url / website_verified / website_checked_at: each distinct domain from website and website_guess is checked by an automated script (DNS, then an HTTP GET to https://, http:// and www., up to 5 redirects, 8-second timeout, one retry with a regular-browser TLS fingerprint on 4xx/5xx). website_verified is true only when the final answer is HTTP 2xx/3xx and the page doesn't look parked, for sale, suspended, expired, "under construction" or a hosting default page. website_verified_url is then the final URL (it can be on another domain when the company forwards its domain to a brand site). Verified means the site answered at check time.
• E-mail rule (company data only). DENUE's e-mail is free text and often the owner's or an employee's own mailbox. email is returned only when both hold: (1) the local part is a role/generic mailbox: every letter run splits into words of a Spanish/English department vocabulary (contacto, ventas, info, administracion, atencion, clientes, recepcion, facturacion, compras, rh, recursos humanos, gerencia, direccion, soporte, servicio, contabilidad, finanzas, cobranza, legal, marketing, hola, contact, sales, admin, office, …) plus qualifiers (digits, ./_/-, city or branch words such as cdmx, mty, sucursal), with at least one department word: contacto@, ventas2@, atencionaclientes@, facturacion.cdmx@ pass; caramosg@, juan.perez@, ventas.juan@, c.ventas@ don't; (2) the domain is the company's own: not free-mail/ISP/placeholder and not a domain shared by many unrelated companies (an accounting firm's). Otherwise email is null and email_is_role is false; email_domain stays only if the domain is corporate. Of the 411,642 default-universe establishments with an e-mail in DENUE, 104,991 (25.5%) carry a role mailbox; the rest are personal or free-mail and are never returned.
• scian_label_en is the English label of the 3-digit subsector; scian_label_es is INEGI's official 6-digit class label. SCIAN is Mexico's NAICS; codes are SCIAN 2023.
• registration_date is the month the establishment entered DENUE, not its incorporation date.
• Rows are establishments. A chain appears once per branch; use one_per_company to collapse.

Limitations

• Rows are establishments, not companies: a retail chain has one row per store. one_per_company collapses by legal name (exact match).
• About 3% of the legal names that pass the legal-entity rules may still be a person's business; INEGI removes the corporate suffix, so this can't be fully separated.
• No RFC (tax id) in DENUE. No revenue; size is the INEGI personnel bracket of the establishment.
• DENUE is refreshed roughly once a year; some contacts are older than the edition date.
• Website checks are newer than the DENUE edition (website_checked_at vs data_as_of): a verified site can belong to an establishment that has since closed.

Data freshness

DENUE edition 05/2026 (published 2026-05-20; Sinaloa corrected 2026-07-01). INEGI refreshes DENUE roughly yearly, mostly for large establishments. Every row carries data_as_of and source; the run log and the OUTPUT record also show the data_as_of of the release that was queried.

Privacy

Company data only. Establishments of natural persons (personas físicas) and rows that are not a confirmed legal entity are never returned, and there is no input to change that (legal_entities_only: false is rejected with an error). You are responsible for using the data lawfully (LFPDPPP, anti-spam rules, opt-out requests).

FAQ

Is this the official DENUE? It is built from INEGI's open bulk download, cleaned and enriched. It is not an INEGI product and INEGI does not endorse it.

Why do some big companies have no legal name? Some establishments are registered by INEGI without razón social. Without it we can't tell a company from a natural person, so those rows are not returned.

Can I look up an RFC? DENUE does not publish RFCs.
